Note that when including mass forward of a particular section we must include all mass
transmitting loads to the section, e.g., fuze, bushings, and cups. The pressures applied to
our model of the M1 projectile are shown in Figure 4.16.
Now let us examine specic locations of interest along the shell where experience tells us
failures might occur. For convenience, these have been tabulated in Table 4.1 and tailored
to each individual location with the symbol, source load, and type of stress noted.
At location 1, these are the formulas used to calculate stresses due to the setback of ller ...
